Virtual Linear Pump Setup - Toshiba GX9 ASD Quick Start Manual

Virtual Linear Pump Setup

Toshiba International Corporation's Virtual Linear Pump algorithm allows for direct and precise
control of pressure, flow rate, or level. This is achieved without the concerns, instabilities, or
complexities that are traditionally associated with pumping system control. This section provides useful
setup and operational information for the Virtual Linear Pump system.
The system is initially configured using the (Program  Virtual Linear Pump Setup Wizard. Once
d
the Wizard is started, it must be completed for normal Virtual Linear Pump operations to function.
However, the parameters addressed while using the Wizard or the Virtual Linear Pump Settings menu
selection are also accessible via their associated direct access numbers for specific adjustments when
required.
If using direct access numbers or the Virtual Linear Pump Settings to configure the Virtual Linear
Pump algorithm, parameter F911 must first be set to 255:Virtual Linear Pump to accept the new or
changed Virtual Linear Pump parameter settings. Upon completion of the parameter changes, set
parameter F911 to 1 or 2 to use the changed (new) settings for normal Virtual Linear Pump operations
(Zero may be selected at F911 to save the changes to be used later).
The setup procedure and the Wizard setup screens are shown below.

Figure 26. Input the Electrical Specifications of the Motor.
1. From the nameplate of the motor,
enter the FLA.
2. Select Pressure, Flow, or Level.
3. Select the command source: EOI, VI/
II, RR, or Com. Opt.
4. Set the Low Frequency Limit. 15 Hz
fits most applications.
5. Click Next to continue.
Figure 27. Input the Specifications of the Transducer.
6. Set the unit of measure for the
transducer: pressure, flow rate, or
level (i.e., PSI, GPM, Inches of Water
Column, Feet of Water Column, or
Cubic Feet per Minute, °C, °F, or
Custom).
7. Select the transducer output signal
type: current or voltage and the range.
8. Set the maximum reading of the
transducer.
9. Set the minimum reading of the
transducer.
10.Click Next to continue.
Note: The Custom selection allows for a
user-created unit of measure for
the process variable as measured
by the transducer.
